could she be pregnant by the summary above??? does girls usually
has TENDER BREAST before GETTING THEIR PERIOD and gone away after mentrual flow? or DOES ALL PREGNANT WOMAN has TENDER BREAST ALL THE TIME WHEN SHE BEING PREGNANT?? HELP PLEASEEEEE!!!!

If you don't want to get her pregnant, use a condom or real birth control methods. Using Withdrawal methods is gonna get her pregnant. Sorry to tell ya this, but CONDOM please I got pregnant with withdrawal method so it's not safe and totally ineffective.

You posted that intercourse took place on 11/15 and ovulation potentially occured from 11/16 to 11/21.
Don't you realize that sperm lives longer than one day? In the proper conditions it can live for 5 days. So the sex on 11/15 could of resulted in pregnancy with an ovulation day on 11/16,17,18,19.
The withdrawal method is no longer considered a birth control method. It only takes one sperm to conceive and plenty more than that come out with pre-ejaculate.
Use a condom.
